open carry laws are bullshit and shouldn't exist - and i don't care about your constitution, which is about two hundred years out of date. but, regardless, you have to expect that the cops will behave like this. the purpose of the police force is not to keep law and order, it's to protect property. when you live in a country with massive racial correlated inequality, a great deal of what the cops do is uphold it. what you're seeing here is a logical necessity.
